FRAMEWORK FOR BIER FAST REROUTE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240163202 titled 'FRAMEWORK FOR BIER FAST REROUTE
Simplified Explanation
The abstract describes a method implemented by a network node in a BIER domain to handle IP LFA and build BIFTs for forwarding BIER packets to avoid failures.
- Obtaining an IP LFA from a FIB or RIB through a first interface.
- Using the IP LFA to build a BIFT when it is of an expected type.
- Accessing a BIER network topology in an LSDB through a second interface.
- Computing an LFA of the expected type and using it to build the BIFT when the IP LFA is not of the expected type.
- Updating the BIFT in the data plane of the network node through a third interface.
- Forwarding BIER packets using the BIFT to avoid a failure.

Original Abstract Submitted
a method implemented by a network node in a bier domain includes obtaining, by a control plane of the network node, an ip lfa from a fib or rib through a first interface, using, by the control plane of the network node, the ip lfa to build a bifte when the ip lfa is an expected type, accessing, by the control plane of the network node, a bier network topology in an lsdb through a second interface, computing an lfa of the expected type, and using the lfa to build the bifte when the ip lfa is not of the expected type, updating, by the control plane of the network node, the bifte in a data plane of the network node through a third interface; and forwarding, by the data plane of the network node, bier packets using the bifte to avoid a failure.
